Why would tasting it be necessary? Again, you've spent years pimping your product based upon its formula, and then you changed the formula.

It's not a rush to judgment at all. It's leaving a brand that's no longer exactly that brand, and a company that cannot be trusted. Again, Coca Cola learned this. New Coke tested better with people than old Coke in blind tests, but people refused to accept it. Don't blame the people. Blame the company for pissing on customer loyalty to the product itself after the company has tried to build up precisely that. A company can sometimes get away with the "new, improved taste" type of move with lesser known products, but even that tends to fail.

This sort of move isn't a guaranteed failure, but it carries a high risk. For me, as someone who's not a devout drinker of the product, I now know how they are willing to treat their customers, so there's no reason for me to patronize that company when there are so many alternatives.

... life will never be the same after the Great Maker's Mark failure of 2013. Whoa is me.....
